Abstract

BACKGROUND: Open inguinal hernia repair (OIHR) can be conducted under either general anesthesia (GA) or local anesthesia (LA). Despite a lack of evidence supporting improved perioperative outcomes, GA is the predominant anesthesia type used in OIHR. Frailty is defined as a clinically recognizable state of age-related increased vulnerability. This study aimed to compare the 30-day perioperative outcomes of frail patients undergoing OIHR with either GA or LA. METHODS: Patients who underwent initial OIHR were identified in the ACS-NSQIP database from 2005-2021. Patients with a Modified Frailty Index (mFI)≥2 were included. Patients were divided based on GA or LA administered. Multivariable logistic regression was used to compare 30-day perioperative outcomes between frail patients undergoing OIHR under GA or LA. RESULTS: Among 20,129 frail patients who underwent initial OIHR, 13,473 had GA, and 3686 had LA. The 30-day mortality rates for LA and GA were low. However, frail patients who underwent LA had a lower risk of bleeding (aOR 0.282, P=0.04), superficial surgical site infection (aOR 0.450, P=0.03), and discharge not to home (aOR 0.792, P<0.01). In addition, frail patients who underwent LA had shorter operation time (58.42±25.26 vs 67.60±37.17 mins, P<0.01) and a shorter length of stay (0.45±2.30 vs 0.57±2.96 days, P<0.01). CONCLUSION: Although GA is the dominant anesthesia use (4:1) in OIHR among frail patients, LA emerges as a safe alternative to GA for these patients, offering potential benefits such as reduced complications and increased day-case surgery volume, which may be associated with decreased healthcare costs.
